Privacy policy

Summary
There are no accounts, we do not ask for your name or email, and the site shows no ads. Here is what happens with data.
What is saved in your browser
We keep the country you choose for the leaderboard in your browser's local storage. It stays on your device, and you can delete it any time from your browser settings. Our code does not set cookies.
Rooms with friends
To play at a distance we use Supabase's realtime service. During a game, the room code, a temporary random identifier and the moves are sent between the two players. They are not stored in a database and are not linked to your identity.
Country leaderboard
When you win a game in an online room against a friend, one win is added to the counter of the country you chose (if you choose none, we use the country of your browser language when it matches one in the list; otherwise nothing is counted). These are totals per country: we do not store who played or from where.
Hosting
The site is served through Cloudflare Pages. Like any web server, Cloudflare may log technical connection data, such as the IP address, to run and protect the service.
To know how many people visit the site we use Cloudflare Web Analytics, which measures aggregate visits without cookies and without building a profile of each person.
Your rights and changes
Because we do not keep personal data linked to you, there is no profile to view or delete; clearing the site's data in your browser removes what is stored on your device. We may update this policy and will show the date at the top of the page.
